[Mil MYC-JX8MPQ Review] Building a QT development environment [Copy link]

 

This board is still very powerful. I hope to learn some other things through this board and try more open source projects. This time I will build the QT environment first.

First of all, you need a virtual machine. The official recommendation is 18.04. We choose Ubuntu 18.04 and start building. First of all, it is the basic compilation environment. Install the SDK compilation environment given. As shown below, we copy the SDK with QT in the name. Only ordinary users are needed. Install as follows. I also modified the installation path, which is currently under home/imx8mp/opt_5_10.

The next step is to enable the environment variables and test whether they are valid, because we can modify the kernel later through the cross-compilation tool chain.

As shown above, we only need to source it. If the version appears, the test will pass.

The next step is to install QT. The current version is QT5.9.4 provided by Mir, but the version in the actual development board is QT5.15.

Just follow the steps to complete all the installation steps above. The next step is to configure the cross compiler. As follows:

Here we need to fill in the gcc compiler tool chain under the location where we just installed the tool, and then fill in a g++ one below.

A new compiler also needs to be added to Kits. I did not choose this QT version myself, it was discovered by QT itself. Finally, we create a new project: as follows

sudo apt-get purge libc6-dev

sudo apt-get install libc6-dev

sudo apt-get install libc6-dev-i386

There may be errors in the compilation, and we need to install some additional libraries ourselves.

After the compilation is completed, we can copy it to the board and execute it.

I didn't connect a display, so I can use qDebug() to output debugging information to see whether the program is executed or not.

Plug in the USB drive and it will mount automatically.

After that, we can check the file information under the path, and it is indeed the executable file on the ARM side.

Finally, we execute it and find that it prints the words we input. So far, the QT environment has been built.

Finally, we found that it has a lot of libraries. Later, we can reduce our own compilation and experience it with our own environment.

QT6 is out. Have you ever thought of using Qt6 to make columns?
